# gt-node: General Translation Node.js SDK: getMessages
URL: https://generaltranslation.com/en-US/docs/node/reference/functions/get-messages.mdx
Docs index: https://generaltranslation.com/llms.txt
Description: Get a General Translation resolver for messages registered with msg for the current request locale. API reference for getMessages.

An async function that returns a resolver for pre-registered messages. Use it together with [`msg`](/docs/node/reference/functions/msg) to register strings at build time and resolve their translations at runtime.

## Overview [#overview]

Register strings with [`msg`](/docs/node/reference/functions/msg) at module scope, then await `getMessages` inside a [`withGT`](/docs/node/reference/functions/with-gt) scope to get a synchronous `m(encodedMsg, options?)` resolver.

```ts
import { msg, getMessages } from 'gt-node';

// Register at build time (or module scope)
const greeting = msg('Hello, world!');

// Resolve at runtime
const m = await getMessages();
const translated = m(greeting);
```

Signature:

```ts
getMessages(): Promise<MFunctionType>

type MFunctionType = <T extends string | null | undefined>(
  encodedMsg: T,
  options?: GTTranslationOptions
) => T extends string ? string : T;
```

*Note: `getMessages` must be called within a [`withGT`](/docs/node/reference/functions/with-gt) callback so it knows which locale to use.*

## How it works [#how-it-works]

- **Two-step pattern.** [`msg`](/docs/node/reference/functions/msg) registers a string for build-time translation; `getMessages` resolves it at runtime for the active locale.
- **Module-scope strings.** This pattern suits strings defined at module scope — constants, enums, and error messages — that must be translated per request.
- **Null passthrough.** If `null` or `undefined` is passed to `m`, it returns `null` or `undefined` respectively.

## Parameters [#parameters]

`getMessages` takes no parameters. The returned `m` resolver takes:

| Parameter | Description | Type | Optional | Default |
| --- | --- | --- | --- | --- |
| [`encodedMsg`](#encoded-msg) | An encoded message string returned by [`msg()`](/docs/node/reference/functions/msg). | `string \| null \| undefined` | No | — |
| [`options`](#options) | Variable values and translation options to interpolate into the resolved message. | `GTTranslationOptions` | Yes | `{}` |

### `encodedMsg` [#encoded-msg]

**Type** `string | null | undefined` · **Required**

An encoded message string returned by [`msg`](/docs/node/reference/functions/msg). Returns `null`/`undefined` if given `null`/`undefined`.

### `options` [#options]

**Type** `GTTranslationOptions` · **Optional**

Variable values to interpolate into the resolved message using `{key}` syntax, plus translation options such as `$context`, `$id`, `$locale`, and `$maxChars`. When the encoded message already carries interpolation options (from `msg('...', { ... })`), those are used and this argument is ignored.

## Returns [#returns]

**Type** `Promise<MFunctionType>`

Resolves to the `m` message-resolution function. `m(encodedMsg, options?)` returns the decoded and interpolated translation, preserving `null`/`undefined` inputs.

## Examples [#examples]

```ts title="messages.js"
// Register messages at module scope
import { msg } from 'gt-node';

export const GREETING = msg('Hello, world!');
export const WELCOME = msg('Welcome, {name}!');
```

```ts title="handler.js"
// Resolve messages for the request locale
import { withGT, getMessages } from 'gt-node';
import { GREETING, WELCOME } from './messages';

function handleRequest(locale) {
  return withGT(locale, async () => {
    const m = await getMessages();
    return {
      greeting: m(GREETING),
      welcome: m(WELCOME, { name: 'Alice' }),
    };
  });
}
```

```ts title="handler.js"
// With variables — pass values as the second argument
import { msg, getMessages, withGT } from 'gt-node';

const ORDER_STATUS = msg('Order {orderId} is {status}.');

function getOrderMessage(locale, orderId, status) {
  return withGT(locale, async () => {
    const m = await getMessages();
    return m(ORDER_STATUS, { orderId, status });
  });
}
```

## Notes [#notes]

- [`msg`](/docs/node/reference/functions/msg) registers a string for build-time translation; `getMessages` resolves it at runtime.
- This pattern is useful for strings defined at module scope (constants, enums, error messages) that need per-request translation.
- If `null` or `undefined` is passed to `m`, it returns `null` or `undefined` respectively.
